I MAED A GAM3 W1TH Z0MB1ES 1NIT!!!1, has managed to sell 200,000 copies, developer Ska Studios reveals. In fact, 40,000 copies have been sold so far this year (based on this data of its performance last year), indicating the game is still pretty darn popular on Xbox Live.
We would say that the game's success lies in its titular undead enemies, but the undead hordes have managed to claw and bite their way into everything nowadays. Instead, we'll point to the game's low price of a buck as being the primary factor for its strong sales. Well, that and its awesome soundtrack.
